Example for a cyclic data transmission to a target code

Conversion

In the example, the conversion is made at FB FEVAN1.

l

The data format of the target code is important for the conversion (see attribute table).

l

Adapt the input signal to the data format of the target code:

– C1093 (numerator).

– C1094 (denominator).

l

C1094 also fixes the decimal positions of the target code:

– Set C1094 according to the existing decimal positions of the target code. The number of

decimal positions can be obtained from the code table.

– 0.0001

¢ no decimal positions.

– 0.001

¢ one decimal position.

– 0.01

¢ two decimal positions.

– 0.1

¢ three decimal positions.

– 1

¢ four decimal positions.

l

For target codes with % scaling the formula for conversion must include a scaling factor (see
example 1).
